VAPOR-BURNING LAMP- 7 Application filed November 12, 1906. Serial No. 343,086.

serving to secure in position the annular draft-shield or ring 8 which projects partly above and partly below the upper edge of the hood, to thoroughly insure against undue draft against the top of the hood. The disk 6 is provided with tubular sockets 9 through which pass the gas-pipes or branches 10 whereby the hood is capable of adjustment along said branches, and when once adjusted is secured thereto by the clamping screws 11. The upperends of the branches lead to a common chamber or box 12 into which the main gas supply-pipe P enters. The lower ends of the branches lead to a second boX or chamber 12 from the center of which projeots upwardly between the branches the gas valve-casing 13 provided with a cock or rockvalve controlled by the lever arms 14 preferably equipped with hand-chains or pendants 15 as well understood in the art. The needlevalve 16 of the valve-casing 13 is controlled by an adjusting screw 17 of any approved design, these features being well understood and forming no part of the present invention. The pilot or lighter is represented by p, and can also be of any conventional design.

Adapted to be secured by means of screws 18 in any adjusted position along the branches 10 is a basin shaped deflecting disk 19 having a bottom hook 20 from which depends the incandescent mantle M, the purpose of the adjustment being to allow for variable lengths of mantles, and the purpose of the basin-shaped disk being to deflect the combustion products against the walls of the hood 1 and the globe G so that the available heat units of said products of combustion may be conserved to the best advantage. That is to say, they are deflected so as to prevent their too direct passage out of the lamp, and are forced against the hood whereby the branches 10 are constantly enveloped by highly heated gases both above and below the deflecting disk.

The globe G is supported directly over a rarefied-air chamber or casting 21 on whose upper surface are hinged a series of locking arms 22 swinging in the plane of said surface, each arm being provided with a shoulder s which, when the arm is swung radially outward frictionally engages the inner wall of the globe G thus locking the same in position. The upper flange of the globe may enter the hood 1 as shown in Fig. 1. Projecting up- To all, whont it may concern.-

Be it known that I, RICHARD W. ZIERLEIN, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Vapor- Burning Lamps, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention has relation to improvements in gas (and other vapor-burning) lamps, and. it consists in the novel details of construction more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure 1 is a half section and half elevation of my improved lamp; Fig. 2 is a vertical middle section of the rarefled-air chamber cooperating with the gas burner; Fig. 3 is a horizontal section enlarged, taken on line 33 of Fig. 1; Fig. 4 is a horizontal section on line 44 of Fig. 1, with globe broken partly away, and Fig. 5 is a top plan with shade omitted.

The present invention has particular relation to store and street lamps using an incandescent mantle, and' among the several objects thereof are the production of a lamp which will be proof against undue influence of draft; one in which the supply of air to the gas may be .regulated according to the character and candle power of the gas; one which will conserve to the best advantage the heat generated by the combustion products; one which provides for a novel method of preheating the gas before ignition, one making special provision for securing the globe surrounding the burner; one preventing an undue back-draft; one whose body will not cast a shadow upon the ceiling; one which is dust proof, and one possessing further and other advantages better apparent from a detailed description of the invention which is as follows:

Referring to the drawings, 1, represents the top or hood the same having a basal flange 2 provided with a series of openings 3 through which the light can pass and thereby prevent the casting of a shadow against the ceiling. The flange 2 is formed into a deending rim 4 which receives the upper lip of the shade S, the latter being held in position by binding screws 5 as shown. The hood 1 is capped by a disk 6 which is secured to said part 1 by bent brackets 7, the latter likewise ward from the center of the top wall of the chamber 21 and projecting partially into the chamber is the burner 23 which enters the base of the mantle M, the burner being of ordinary design and provided with a wire gauze 24 as usual. The mixture of gas and air is conducted to the burner through an inner tube 25 whose bottom communicates with a depending mixing chamber 26 cast with the chamber 21. i In fact the parts 21, 23, 26 are a single casting, the tube 25' being inserted thereinto. To exclude the dust from the mixing chamber the latter is preferably provided with a wire screen v27 having a central opening for the free passage therethrough of the tip of the valve-casing 13.

It will be seen that the chamber 21 can be slipped and adjusted along the pipes 10 and when in proper position may be clamped thereto by the securing screws 28. The purpose of the adjustment is to vary the distance of the point of discharge of the gas from the casing 13 from the intake end of the tube 25, gas having plenty of air entering into its composition requiring a smaller quantity of air for mixing with the gas; and gas rich in hydrocarbons requiring a greater admixture of air before being delivered to the burner. By moving the chamber 21 up and down alon the pipes 10, the base of the tube 25 will e brought farther from or closer to, the point of discharge of the valve-casing 13 (whose position is fixed) and hence regulate the quantity of air designed to mix with the gas in the chamber 26 before passing into the tube 25. In Fig. 2 the tube 25 is removed farther from the casing 13 than in Fig. 1, so that in the latter case a relatively less quantity of air will pass into the tube to be mixed with the gas.

When the walls of the chamber 21 become thoroughly heated a portion of the air within will naturally be expelled and pass out through the burner, and there will remain in the chamber a rarefied body of hot air which will act as a hot blanket serving to maintain at a high temperature the constantly inflowing mixture of air and gas, thereby in a measure serving as a supplemental heater for the air and gas mixture passing into the burner, the gas component having been previously heated in passing through the branches 10, 10. The air within the cham formed at the bottom of ber 21 too, serves as a cushion against any back-draft, which latter will preferably at- 5 5 tack the rarefied contents of the chamber than it will the current passing up the tube 25.

The operation of the lamp is fully indicated by course limit myself to the number of pipes 10.

Having described my invention, I claim: 1. A lamp having one or more gas-supply pipes, a gas-valve at the lower ends of the p pes, a rarefied-air chamber coupled to the pipes above the valve, a mixing chamber said air-chamber, a burner leadingfrom the ber, and a tube establishing communication between the mixing chamber and the base f the burner.

the course of the arrows in Figs. 1 and 2 which show the circulation of the gas and 60 top of the air-cham-' 2. A lamp having a series of gas-supply pipes, a gas-valve at the lower ends thereof, a valve-casing for said valve; a rarefied-air chamber coupled to and adjustable along said pipes, a mixing chamber depending from the bottom wall of the air-chamber, and loosely receiving the adjacent end of the gas valve-casing, a burner leading from the top of the-air chamber, a tube establishing communication between the mixin the base of the burner, and a ltering screen at the lower ed e of the mixing chamber and encompassing t e valve-casing.

3. In a lamp, a series of gas-supply pipes, a

valve for controlling the supply, a rarefied- 9 air chamber adjustable along the pipes and movable to and from the valve, a mixing chamber at the base of the air chamber for receiving the flow of gas and air adapted to mix therewith, a centrally disposed burner tube projecting upwardly from the air-cham ber, and a series of globe-fastening latches distributed on top of the air-chamber around the burner tube.
